Abstract

An enzyme-linked immunosorbent assay (ELISA) for the quantitation of 2,4-dinitrophenyl (DNP)-specific murine immunoglobulin (Ig) E is described. The assay uses β-galactosidase, which is conjugated to goat anti-rabbit γ-globulin (GARG) via a method using a mild heterobifunctional cross-linking reagent, m-maleimidobenzoyl-N-hydroxy-succinimide ester (MBS). The assay has a sensitivity for detection of about 200 pg/ml of anti-DNP IgE. Analyses of murine serum samples using this ELISA correlate well with those obtained using the passive cutaneous anaphylaxis (PCA) reaction in rats. With the use of automated 96-well reader, data acquisition is rapid and, therefore, this ELISA is ideal for analyses of large numbers of samples. The assay can be easily modified for the measurement of other Ig classes and of IgE of other antigen specificities.
